A tremor in Lebanon measuring 3.8 on the Richter scale was felt in northern Israel on Friday morning. No one was injured and no damage was reported. On Thursday, four similar tremors were felt in the North and parts of central Israel. The first tremor Thursday, measuring 3.9 on the Richter scale, occurred at 4 p.m. and it was followed two-and-a-half hours later by three more, measuring 3.8, 4.2 and 4.1 respectively. Last February, a quake measuring 5.3 on the Richter scale was felt in the North. The source of that quake was also Lebanon, about 15 kilometers northeast of Tyre. In the same week, a tremor, also originating in the Tyre area, and measuring 4 on the Richter scale, was felt in northern and central Israel. At the start of the year, there was a series of four quakes in the Dead Sea area measuring between 3 and 4.3 on the Richter scale. Seismologists said there was no link between the quakes and that a series of several tremors in no way indicates that a large earthquake is likely to hit the region.
